Seattle Grace-Mercy Death (a Grey's Anatomy fanfic)

Since the death of George O'Malley, many things happened to his friends and coworkers.
Some died, some quit, some got married...But everybody is missing him.
So when he shows up at Christina Yang's door one day everybody is shocked to see him breathing. But not everyone's shock is expressed in the best way. Some might never be able to forgive him for making him miss him so much, and some might have changed so much their relationship can't be rekindled.
But what about George, is he really okay?
